25 groups of AC-25 asphalt mixture are designed by referencing the orthogonal design method,the high temperature rutting and freeze-thaw cycle test are carried out,the related model of the fractal dimension and the road performance evaluation index including dynamic stability and freeze-thaw cycle dynamic stability ratio is established by using fractal theory.The high temperature stability and water stability performance of AC-25 asphalt mixture can be predicted according to the gradation designed.This can reduce the test workload,improve work efficiency,and offer the reference for engineering design.
